Single-Layer Thin PCB Prototype

I need a custom-shaped, single-layer printed circuit board produced quickly so I can test the mechanical fit and basic electrical routing for a new product I am developing. The overall board must stay as thin as practical; once we speak I will confirm exact thickness and any stack-up limits from my enclosure, but the goal is to minimise profile without sacrificing manufacturability.

Here is what I will supply once we start:
• A rough outline drawing and simple netlist showing the required connections
• Components and preferred connector locations

What I expect from you:
• Review of my outline and placement to flag any manufacturability concerns
• At least three fabricated prototypes shipped to me for bench testing

Please use whichever professional tools you are comfortable with

I will mark the project complete when the Gerbers pass my review, the boards arrive defect-free, and the simple continuity test matches the netlist.
